Video posted online Tuesday showed rebels firing on government soldiers in the Damascus neighborhood of Barzeh, a restive part of the capital. The video was edited together from a series of clips said to show different scenes of the same battle, including images of rebels excitedly spotting a soldier's hand as it peeked from behind a wall and footage of weapons they described as "the spoils" of battle. The rebels said they were from a number of Islamist groups fighting side by side.

What We Know

Barzeh has been the scene of fiercefighting
since the Syrian uprising began in March 2011. The Syrian Observatory for Human Rights, a group based in Britain, reported fighting in the neighborhood on Wednesday. The rebels in this video said they "followed" Lewa al-Tawheed, an Islamist group.

What We Don't Know

We do not know how many people may have been killed or injured in this battle, or how frequent such battles might be in Barzeh. We do not know if each scene was filmed by the same person, or even on the same day. We do not know the relative strength of the rebels or the government in this area.

Other Videos

The Local Coordination Committees, a network of activists throughout Syria, drew attention to two more videos from Barzeh on their
Twitter feed. One showed the shelling of a neighborhood centered on a row of burned-out high-rise apartment buildings. Another showed the devastation on a local street.
